Application filed November 4, 1908. Serial No. 460,986.

To all whom it may concern Be it known that I, GEORGE B. BASSETT, a

citizen of the United States, residing at Buf-' falo, in the county of Erie and State of New York, have invented a new and useful Water- Meter, of which the following is a specification, reference being had to the drawings accompanying and forming a part thereof.

My invention relates to meters for measuring the ordinary and the extraordinary flows of water in pipes.

The principal object of my present invention is to provide a meter for measuring and registering all ordinary flows of water through a pipe and which will also pass dirt, sticks, and stones, and measure all extraordinary flows of water through the pipe with the least possible obstruction to the current by automatically opening the current Way and automatically registering the increased flows.

()ther objects are to improve the construction and arrangement of these meters for the purpose of reducing the cost of manufacture, allowing the more read assemblage, separation, and adjustment of parts, increasing the eihciency and durability, and giving other advantageous results.

I attain these objects by the mechanism illustrated in the'accompa-nying drawings, in whicha Figure l is a vertical longitudinal section of the outside case of the. meter showing the submerged working parts in position. Fig. 2 is a top view of the meter with the cover and indicators removed; Fig. 3 is a side elevation of the meter showing the indicators and their connecting gearing; Fig. 4c is an end view of the inlet opening to the meter showing how the current way changes from a circular to a rectangular section.

Similar numerals refer to similar parts throughout the several views.

1 is the main outside case of the meter which is provided with a cover 2 securely fastened to same by screws passing through holes 2) in flange 1. Water inlet opening 5 and water outlet opening 6 are circular and are connected by rectangular current way 7 which has substantially parallel sides and is substantially equal in area to circular inlet 5 and outlet 6 and in which is hung swinging valve 8 by trunnions 9 and 10 resting in bearings formed in the sides of outer case 1. The maximum are through which valve 8 may swing is limited by projections 11 and 12 formed on its sides striking the top and bottom of recesses 13 and 14. formed in the sides of outer case 1. On the free end of swing valve 8 is mounted current measuring wheel 15 and its toothed wheel 16. Concentric with the center about which valve 8 swings is toothed gear 17 rigidly mounted on stufiing box shaft 18. On the top of swing valve 8 are mounted intermediate toothed wheel reducing gears and pinions 19, 20, and 21, which transmit the motion of current measuring wheel 15 and its toothed gear 16 to gear 17 and its stuffing box shaft 18. Trunnlon 10 passes through stuffing box 22 to the outside of case 1 and on the outer end of same is rigidly and adjustably mounted swinging lever 28 which carries on one of its free ends friction spur toothed wheel 24 which thus rises and falls with swinging valve 8. Stuffing box shaft 18 passes through stuffing box 25 in trunnion 10 and on the outer end of same is rigidly mounted spur toothed wheel 26 and beveled toothed wheel 27. Beveled toothed wheel 27 meshes with register beveled toothed wheel 28 which is rigidly mounted on register shaft 29 which operates the ordinary register 30 which is thus positively connected with and positively registers the number of turns current measuring wheel 15 makes during any given period of time. Spur toothed wheel 26 meshes with and operates friction spur toothed wheel 24 against the side of which is pressed friction register wheel 31 which is rigidly mounted on register shaft 32 which operates actual register 33.

On swinging valve 8 is formed thevprojection 34 which acts as an oscillating cushioning piston in the hydraulic cushioning chamber 35 formed in outer case 1.

36 is a small opening through which the cushioning liquid passes from one side of the piston to the other slowly so as to prevent the sudden rising and falling or clattering of swinging valve 8.

38 is an adjustable counter weight that may be moved back and forth on lever 23 to counterbalance in part swinging valve 8 and its attachments.

In operation, the water enters the meter at inlet opening 5 and passes thence along rectangular current way 7 and under swinging valve 8 operating current measuring wheel 15 at a speed proportionate to the speed of the water through the variable opening 37 between the bottom of current Way 7 and the under side oi the free end of swinging valve 8. fit all ordinary flows, this will be constant as the Weight of swinging valve 8 will keep it at its lowest position which is that shown by the full lines in the drawings. Both registers are set to equally register this constant or ordinary How. Should an extraordinary flow of Water pass through the meter it will raise sviineinp; valve 8 and swinging arm 23 With its rriction spur ivheel 242-, thus causing register friction wheel 31 to travel farther, operating actual register proportionately raster. llen'ister would show the actual amount of outer that passed through the meter; while the difference between the amount indicated by ordinary register 30 and actual register 33 would show approximately the amount used :tor extraordinary purposes.

The maximum height of swinging; valve 8 is shown by dotted lines in Fig. l; and the corresponding; maximum height oil swinging arm :23 and its spur toothed. friction Wheel 2i is shown by dotted lines in Fig.

From the foregoing descrirrtioni it will obvious to persons skilled in the modifications may be made in details of con struction of my improved'ivater met-er v Ithout departing from the spirit or principles of my invention and that some of, the improvements described may be used Without the others.
